Answer 1

Answer:

180 points.

Step-by-step explanation:

Given:

A class will have 1 test and 5 homework assignments to complete.

The test is worth 80 points.

Each homework assignment is work 25% of the test.

Question asked:

How many points may be earned during this unit ?

Solution:

By unitary method:

Points may be earned from 1 assignments = $25\% of 80$ (given)

                                                                       = $\frac{25}{100} \times 80 = \frac{2000}{100} = 20$

Points may be earned from 5  assignments = $5\times 20 = 100$

Points may be earned from 1 test = $80$

Total points may be earned = 100 + 80 = 180

Therefore, 180 points may be earned during this unit.
